Title: Complementary mos logical circuit
Inventor: KOIKE HIDEJI
IPC: H03K19/0948
Filed: 1982-07-20
Abstract: PURPOSE:To attain multi-stage cascade connection, by taking a logical section with series connection of plural N-channel depletion MOSFETs and inserting a P-channel MOSFET between one end of the logical section and an output terminal for decreasing number of elements. CONSTITUTION:The MOSFETs 51, 52, 53 connected in series in the logical section 50 are all turned on when three logical signals A, B, C are at a high level. A connecting point 57 is set to a level higher than the potential of a power supply. Since the MOSFET55 turns on, an output terminal 54 is set to a high level. When at least one of the logical input signals A, B, C is at a low level, the FET is turned off. The potential at the connecting point 57 is fixed to an absolute value of the threshold voltage of the N-channel depletion MOSFET in this case. The FET55 is turned off. The output terminal 54 is kept to a low level with the presence of a resistor 56. The logical signal of the logical input signals A, B, C is obtained at the output terminal 54.

Title: Pattern formation
Inventor: FUSHIMI HIDEKI
IPC: H01L21/302
Filed: 1987-05-22
Abstract: PURPOSE:To form a high-precision submicron-rule pattern and to increase throughput by a method wherein a resist film pattern is formed on a TiN film, the exposed portion of the TiN film is oxidized for the formation of a TiON film on its surface, and the TiN film with the resist film removed is etched into a mask. CONSTITUTION:A coating of titanium nitride (TiN) film 11 is provided on an SiO2 film 2 to be subjected to etching, and a resist film pattern 13 is formed on a portion to be etched of the TiN film 11. Next, the surface of the TiN film 11 is oxidized for conversion into a titanium oxide nitride (TiON) film 12, after which the resist film 13 is caused to peel off and the now-exposed TiN film 11 is etched away in a fluorine-based gas. A process follows wherein the TiN film 11 with the surface thereof converted into the TiON film 12 serves as a mask in a process of etching the SiO2 film 2. This realizes a high-precision masking pattern built of a thin TiN film with very sharp edges. Such a mask may be very fine in pattern and high in precision.

IPC: G03G13/22
Filed: 1983-07-11
Abstract: PURPOSE:To improve a color purity, and to simplify an image formation by making a light transmitting and conductive particle adhere electrostatically onto a photosensitive body, and thereafter, executing an image exposure, and removing the particle whose adhering force to the photosensitive body has dropped or annihilated by the image exposure, from the photosensitive body. CONSTITUTION:When a light transmitting and conductive particle 15 is sprinkled uniformly onto a photosensitive body, impressing a voltage between a particle sprinkler 13 and a conductive supporting body 14 through a photoconductive layer 12 in the dark, the particle is held on the photosensitive body by an electrostatic attraction between the particle and the conductive supporting body through the photoconductive layer of a high resistance state. In this state, when an image exposure is executed through a transmission original 16 and the light transmitting and conductive particle, a charge of the particle of the part which has received a light irradiation is cancelled mutually by a transmission charge in the conductive supporting body and annihilates, through the photoconductive layer of the contact part to the particle which has been made conductive by a particle transmitting light. In the end, when a vibration is given to the photosensitive body by an electromagnetic vibrator 17, the particle whose adhering force to the photosensitive body has been lost by the light irradiation is removed easily by the light irradiation, and in accordance with the original 16, a particle image is obtained on the photosensitive body.

Title: Compression ignition type internal combustion engine
Inventor: KAWAGUCHI AKIO
IPC: F02D41/40
Filed: 1999-05-07
Abstract: PROBLEM TO BE SOLVED: To prevent generation of unburned HCs and dilution of lubrication oil by closing an exhaust valve before an intake top dead center, while opening the intake valve after the intake top dead center and injecting fuel in the vicinity of the intake top dead center, when the exhaust valve and the intake valve are closed. SOLUTION: An exhaust valve is closed before an intake top dead center TDC, while an intake valve is opened when a pressure inside a combustion chamber is equalized to that inside an intake port after passage through the intake top dead center TDC, and fuel injection is carried out in the vicinity of the intake top dead center TDC in which the exhaust valve, and the intake valve are closed. In this process, the combustion chamber is filled with a high temperature burnt gas because the intake valve is closed, so that fuel particle diameter becomes small. Since the exhaust valve is closed before the intake top dead center TDC, a pressure inside the combustion chamber is increased, so that the injected fuel is hardly dispersed. Therefore, the adhesion of fuel particles to the fuel combustion chamber wall face is prevented.  While a piston is lowered subsequently, a fuel evaporation action is promoted, and adhesion of fuel to the inside wall is reduced also in this process. Consequently, generation of unburned HC and dilution of lubrication oil can be deterred.
